Living kidney donors must be evaluated carefully focusing on risk factors for long-term complications. Our transplant center performs 70% of its kidney transplantations from living sources including 19.9% obese donors. We evaluated the long-term follow-up of recipients of organs from 37 living donor patients with obesity defined by a body mass index (BMI) >(More)
Pituitary gonadotrophins (follicle-stimulating hormone, FSH; luteinizing hormone, LH) exist in different molecular forms within the anterior pituitary gland and serum of several non-mammalian and mammalian species, including man. The number and relative abundance of each gonadotrophin species will depend on the specific technique utilized for their(More)
Anterior pituitary (AP) glands were removed from adult female rats at different times throughout the estrous cycle, and the isohormones of follicle-stimulating hormone (FSH) present within them were separated by isoelectric focusing in polyacrylamide gels (PAGE-IEF; pH range 3.0-8.0). Gel eluents were analyzed for FSH content by radioimmunoassay (RIA) and(More)
The living kidney donor represents a good resource for kidney transplantation. These grafts display better function and long-term graft survival at 5 and 10 years of follow-up. Furthermore, living donors prefer the possibility to increase kidney donation for a large waiting list of patients with end-stage renal disease (ESRD). However, kidney donation is a(More)
Myocardial damage was analyzed in the different stages of Chagas' disease. Myocardial biopsies from chagasic patients, whose clinical histories were initially unknown to the examiner, were examined and evaluated by electron microscopy using a table in which 244 characteristics were considered. When the ultrastructural results were associated with their(More)
Prevalence and severity of erectile dysfunction increase with advancing age. Patients with end-stage renal disease (ESRD) experience disturbances in erectile function related to organic factors including as uremia, hypertension, endocrine, and nonorganic factors like depression. Recipients of kidney transplants show a high prevalence of erectile(More)
In the present study, we investigated the biological characteristics of different molecular forms of chorionic gonadotrophin (HCG) secreted by the human cytotrophoblast during its morphological and functional differentiation in culture. Highly purified cytotrophoblasts were prepared from term placentae and cultured for 24 to 96 h in the absence or presence(More)
Anterior pituitary glands were removed from neonatally androgenized (100 micrograms testosterone propionate) female rats and normal controls at 5, 10, 18, 21, 30, 60 and 90 days of age, and the multiple forms of FSH present within them were separated by chromatofocusing (pH range 7.5-4.0). Additional pituitary glands from intact adult males (90 days old)(More)
